***

## 1. Task Completion

### Status: PASS

| Category       | Required | Completed | Status |
| -------------- | -------- | --------- | ------ |
| Setup          | 2        | 2         | PASS   |
| Foundation     | 5        | 5         | PASS   |
| Implementation | 6        | 6         | PASS   |
| Testing        | 5        | 5         | PASS   |

### Incomplete Tasks

None.

***

## 2. Deliverables Verification

### Status: PASS

#### Files Created

| File                                    | Found           | Status |
| --------------------------------------- | --------------- | ------ |
| `apps/web/src/lib/combatPlayback.ts`    | Yes (non-empty) | PASS   |
| `apps/web/tests/combatPlayback.test.ts` | Yes (non-empty) | PASS   |

Both files are inside the declared `apps/web` package scope. No files were modified outside the package.

### Missing Deliverables

None.

***

## 3. ASCII Encoding Check

### Status: PASS

| File                                    | Encoding | Line Endings | Status |
| --------------------------------------- | -------- | ------------ | ------ |
| `apps/web/src/lib/combatPlayback.ts`    | ASCII    | LF           | PASS   |
| `apps/web/tests/combatPlayback.test.ts` | ASCII    | LF           | PASS   |

`file` reports ASCII text for both; a `[^\x00-\x7F]` grep finds nothing; no CRLF present. The one non-ASCII test literal was rewritten with `é` escapes.

### Encoding Issues

None.

***

## 4. Test Results

### Status: PASS

| Metric                 | Value              |
| ---------------------- | ------------------ |
| Web project test files | 137 passed / 137   |
| Web project tests      | 2213 passed / 2213 |
| New session tests      | 27 passed / 27     |
| Failed                 | 0                  |

Run via `npx vitest run --project web` from the repo root (the root `vitest.config.ts` supplies the happy-dom environment for web tests; running vitest from inside `apps/web` bypasses that config and is not a valid invocation). Focused run `npx vitest run tests/combatPlayback.test.ts` also passes under the node environment, confirming environment independence of the pure module.

### Failed Tests

None.

***

## 5. Success Criteria

### Functional Requirements

* [x] Every protocol `ToolName` classifies to a strike kind; unknown/custom MCP tools fall back to the generic strike (classification table test).
* [x] `tool_result` `ok: false` classifies as counterattack; `ok: true` produces no strike.
* [x] Combo accumulation caps at `COMBO_MAX_STAGE` inside `COMBO_WINDOW_MS` and resets after quiet.
* [x] Simulated 45-minute stream (1140 events) yields bounded fresh emissions, bounded allowed cues, and bounded accumulator/history sizes.
* [x] Stage props are monotonic non-decreasing and hit each milestone exactly once at its boundary.
* [x] Rate-limit decisions are independent per category.

### Testing Requirements

* [x] Unit tests written and passing (27 tests).
* [x] Privacy tests prove labels contain no absolute paths, no secret-shaped content, and respect the length bound.

### Non-Functional Requirements

* [x] Purity contract enforced by a comment-stripped source-scan test (no store/React/DOM/audio imports, no ambient clock or RNG).
* [x] All tuning values are named exported constants.

### Quality Gates

* [x] All files ASCII-encoded.
* [x] Unix LF line endings.
* [x] Code follows project conventions (Biome clean, root format:check passes across 776 files).

## 6. Conventions Compliance

### Status: PASS

| Category       | Status | Notes                                                                           |
| -------------- | ------ | ------------------------------------------------------------------------------- |
| Naming         | PASS   | camelCase functions, SCREAMING\_SNAKE constants, matches `legionCamps.ts` style |
| File Structure | PASS   | Pure lib in `apps/web/src/lib/`, test in `apps/web/tests/` per split convention |
| Error Handling | PASS   | Total functions; invalid input degrades to safe fallbacks, never throws         |
| Comments       | PASS   | Doc comments explain design-section rationale, no commented-out code            |
| Testing        | PASS   | Vitest, focused pure-lib test file mirroring existing conventions               |

### Convention Violations

None.

***

## 7. Security & GDPR Compliance

### Status: PASS

**Full report**: See `security-compliance.md` in this session directory.

#### Summary

| Area     | Status | Findings                             |
| -------- | ------ | ------------------------------------ |
| Security | PASS   | 0 issues                             |
| GDPR     | N/A    | 0 issues (no personal data handling) |

### Critical Violations

None.

***

## 8. Behavioral Quality Spot-Check

### Status: PASS

**Checklist applied**: Yes **Files spot-checked**: `apps/web/src/lib/combatPlayback.ts`

| Category           | Status | File                                 | Details                                                                                                                |
| ------------------ | ------ | ------------------------------------ | ---------------------------------------------------------------------------------------------------------------------- |
| Trust boundaries   | PASS   | `apps/web/src/lib/combatPlayback.ts` | Non-string/empty/hostile tool names and paths handled without throwing; sensitive segments redact                      |
| Resource cleanup   | PASS   | `apps/web/src/lib/combatPlayback.ts` | Combo states pruned on every advance; cue histories pruned and capped - verified by long-stream test                   |
| Mutation safety    | PASS   | `apps/web/src/lib/combatPlayback.ts` | Pure immutable inputs/outputs; no shared mutable state                                                                 |
| Failure paths      | PASS   | `apps/web/src/lib/combatPlayback.ts` | Total functions with documented fallbacks (generic strike, tier 0, "Strike" label)                                     |
| Contract alignment | PASS   | `apps/web/src/lib/combatPlayback.ts` | Strike-kind union matches the exported `STRIKE_KINDS` list (tested); tool mapping covers the protocol `ToolName` union |

### Violations Found

None.

### Fixes Applied During Validation

None required beyond implementation-phase fixes already logged.

***

## Validation Result

### PASS

All 18 tasks complete, both deliverables exist and are ASCII/LF clean, the full web test project passes 2213/2213 with 27 new focused tests, typecheck and Biome gates are clean, conventions hold, and there are no security, GDPR, or behavioral quality findings.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://faction-os.gitbook.io/faction-os-docs/.spec_system/specs/phase24-session01-pure-strike-and-combo-model/validation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
